西門子1FK7伺服電機維修作為一種數(shù)字式執(zhí)行元件，在運動控制系統(tǒng)中得到廣泛的應用。在使用西門子電機的時候，感覺電機工作時有較大的發(fā)熱。實際上發(fā)熱是電機的一個普遍現(xiàn)象，但怎樣的發(fā)熱程度才算正常，以及如何盡量減小步進電機發(fā)熱呢?

　　1、將西門子電機發(fā)熱控制在合理范圍內、1FK7042-5AK71-1EH5維修
　　電機發(fā)熱允許到什么程度，主要取決于電機內部絕緣等級。內部絕緣性能在高溫下(130度以上)才會被破壞。低于130度，電機不會損壞，表面溫度會在90度以下。表面溫度在70-80度都是正常的。滴幾滴水迅速氣化，則90度以上了;當然也可以用測溫槍來檢測。
　　2、西門子電機發(fā)熱隨速度變化的情況
　　采用恒流驅動技術時，電機在靜態(tài)和低速下，電流會維持相對恒定，以保持恒力矩輸出。速度高到一定程度，電機內部反電勢升高，電流將逐步下降，力矩也會下降。
　　3、發(fā)熱帶來的影響
　　電機發(fā)熱雖然一般不會影響電機的壽命，對大多數(shù)客戶來說沒必要理會。嚴重的發(fā)熱會帶來一些負面影響。如電機內部各部分熱膨脹系數(shù)不同導致結構應力的變化和內部氣隙的微小變化，會影響電機的動態(tài)響應，高速會容易失步。
　　4、減少電機的發(fā)熱
　　減少發(fā)熱，就是減少銅損和鐵損。 減少銅損有兩個方向，減少電阻和電流，這就要求在選型時盡量選擇電阻小和額定電流小的電機，對兩相電機，能用串聯(lián)的電機就不用并聯(lián)電機。細分驅動器由于電流波形接近正弦，諧波少，電機發(fā)熱也會較少。 減少鐵損的辦法不多，電壓等級與之有關，高壓驅動的電機雖然會帶來高速特性的提升，但也帶來發(fā)熱的增加。
